Groundnut Oil Manufacturing Process With Flowchart - Goyum
Step 1: Cleaning. After harvesting groundnut are received at processing facilities. Batches of harvested peanuts will contain whole peanuts in the shell, some shelled peanuts, and foreign objects (e.g., leaves, nodes, weed seed, etc.). The peanuts are then cleaned using cleaning machine so that oil is not contaminated with foreign materials.
This step extracts a portion of the oil from the seeds and leaves behind oil-rich cake. Oil Extracting Process: The pre-pressed cake is then subjected to solvent extraction with the help of a solvent extractor. In this step, a food-grade solvent is used to separate the remaining oil from the cake, resulting in a defatted meal and crude oil.
Peanut proteins: Extraction, modifications, and applications: A
The yield of free oil extracted from roasted peanut (150 °C, 20 min) using the AEP method was around 92.2% using the optimized processing conditions: solids-to-liquid ratio = 1:5; pH = 9; temperature = 60 °C, and time = 2 h [33]. Liu et al. (2020) investigated a combination of AEP and membrane separation for peanut protein extraction.
In countries like India and China, more than half of the produced peanuts (nearly 12–14 MMT) are processed using mechanical pressing or solvent extraction to produce edible oil. The residual matter obtained after oil extraction is called peanut meal, or peanut oilcake, and it contains about 47–55% protein (supplementary information 1).
Edible Plant Oil: Global Status, Health Issues, and Perspectives
Pressing extraction of edible oil can be divided into hot-pressed and cold-pressed (Pereira et al., 2014). Cold-pressed is a method of producing oil by low-temperature pressing through an oil mill. The oil plants are not heated, nor are they are stir-fried at low temperature before pressing.
In this time, the chemical method solvent extraction will be a good method to fully extract peanut oils. The solvent extraction method can create the residual oil rate of the groundnut meal below 1%. Therefore, for edible use, the pressed crude groundnut oil needs to be refined by filter presses or oil refining plant.
Groundnut Oil Extraction Plant | Peanut Oil Processing | Oil Press Machine
Groundnut Decorticator. Groundnut decorticator machine is used to remove the hard shell of peanuts and get red skin peanut kernels automatically. The shelled peanut kernel can be applied to the peanut oil production line. Groundnut decorticator is versatile in shelling not only peanuts but other oil seeds like almonds, sunflower seeds.
The oil extraction using cold-pressing method is performed at temperatures below 60 °C while in a hot-pressing condition, high temperatures are applied (Tan et al., 2020). Although peanut oil produced by hot-press is more popular due to its better aroma and flavor, it may lose its micronutrient due to proton denaturation at high temperatures.
- Which method is used to extract peanut oil?
- The conventional extraction methods include the press method, leaching process, and alkali-soluble acid precipitation method [ 27 ]. The press method is to extract part of the oil in peanuts, to achieve the effect of making peanut meal at the same time, which can be divided into hot pressing method and cold pressing method.
- How is cold pressed peanut oil extracted?
- The peanuts are then placed in a conditioning tank, where the pressing temperature and moisture are adjusted to maximize the oil yield. To commercially extract cold-pressed peanut oil, a twin-screw press is used, and the pressing is performed at specific temperatures that do not exceed 60 °C.
- What is peanut oil processing technology?
- This chapter covers peanut oil processing technology. It starts by explaining the pretreatment technology and peanut pressing technology of high temperature and cold pressing peanut oil. It then discusses the peanut oil extraction technology, which includes leaching and separation technology.
- How to make peanut oil in China?
- Currently, there are two pressing methods: high-temperature pressing and cold pressing. More than 90% of oil production in China adopts the traditional technique of high-temperature pressing, and the peanut oil produced with this method has a strong fragrant flavor and is therefore greatly favored by consumers.
